Firmware Flash Compatibility

The IS200VSVOH1BDC integrates into Mark VI deterministic backplane bus cycles. Firmware flash compatibility ensures synchronization with associated TSVO/DSVO terminal boards. Deterministic communication velocity across J3/J4/J5 connectors maintains predictable timing for servo current commands and LVDT feedback acquisition. Triple Module Redundancy (TMR) is supported via JR1, JS1, and JT1 fan‑out connectors, enabling fault‑tolerant turbine operation.

Frequently Asked Questions

Q: Can the IS200VSVOH1BDC be hot‑swapped in a powered VME rack? A: No, insertion or removal must occur only when the rack is de‑energized to prevent bus contention and undefined servo outputs.

Q: How many LVDT sensors can be connected? A: Up to three LVDT/LVDR sensors can be interfaced for valve position feedback.

Q: What is the supported frequency range for speed sensors? A: The board accepts active or passive speed sensor inputs across a 2–14 kHz pulse frequency range.

Field Installation Guidelines

  • Power down the VME rack before handling or insertion.
  • Seat the board using top and bottom levers to ensure full connector engagement.
  • Secure captive screws to resist vibration.
  • Route servo and LVDT wiring with shield continuity maintained to designated grounding points.
  • Verify RUN/FAIL/STATUS LED indicators after startup.
  • Confirm redundancy cabling for JR1, JS1, and JT1 connectors in TMR configurations.
